    •	Collecting and processing the User's personal data, in accordance with Law 78-17 of January 6, 1978 relating to computer science, files and freedoms as amended by the Law of June 20, 2018, order No. 2018-1125 of December 12, 2018 amending Law 78-17 of January 6, 1978 relating to computers, files , freedoms and various provisions relating to the protection of personal data, as well as Regulation 2016-679 of 27 April 2016 relating to the protection of individuals with respect to the processing of personal data and the free movement of such data (the "Regulation" collectively);
    •	View, process and conserve user browsing information on the Site that may be stored via "cookies" files (hereafter “Cookies”).
    The person responsible for processing personal data is Origins, simplified joint stock company with a single shareholder, headquartered in Tower Cb 21 - 16 Place de l'Iris 92040 Paris La Défense Cedex, registered in the Nanterre Register of Trade and Companies under the number 847 888 377  (hereafter "Publisher").
    The Policy may be amended at any time by the Publisher, in particular to comply with any regulatory, judicial, editorial or technical developments. The User should refer to the latest version of the Policy before any navigation.
    This Privacy Policy is an integral part of the Site's Terms and Conditions.
    Personal data protection
    When using the Site by the User, the Publisher may be required to collect and process personal data in order to allow the User to access the services offered by the Site (hereinafter the "Services"). In each data entry form, the Publisher undertakes to limit data collection to what is strictly necessary based on the purpose pursued (data minimization principle).
    1) What data is collected?
    •	Contact data: refers to the mandatory data that the User provides by filling out the contact form, i.e.: civility, name, first name, email address, country of residence.
    •	Data voluntarily published by the User: refers to personal information that the User voluntarily communicates to the Publisher by filling out the free text areas provided for this purpose in the contact form, namely "Object of the request" and "Message". The Editor strongly recommends that the User avoid any communication of any personal data via these text areas or in any event to limit this communication to what is strictly necessary to process the User's request. If Origins were to collect personal data through this, Origins  would ensure that it used only the data strictly necessary to process the User's request (hereafter “Published Data”).
    •	Navigation data: refers to the data that the Publisher collects when browsing on the Site, primarily through cookies, such as the date, time of connection and/or navigation, browser type, browser language, IP address.
    All this data will be collectively referred to as the "Data" below.
    2) Why does the Publisher collect User Data?
    Data collected as part of the use of the Site is processed to meet the following purposes:
    •	Managing user requests via the dedicated contact form;
    •	Contact requests to join the network via the dedicated contact form;  
    •	The development of statistics and attendance measures for the Site;
    When collecting data, the User is informed whether certain data must be provided or if it is optional. Data identified by an star within the contact form is mandatory. In the absence of information on the mandatory headings, access to the Services and their use by the User may be restricted.
    The use of contact data and data voluntarily published by the User is necessary to carry out the contract between the User and the Publisher. This is therefore the main legal basis for data processing operated by the Publisher. In fact, in accordance with the General Terms of Use, the Publisher offers users of the Site the opportunity to obtain information about the company, to ask questions, to make comments and more generally, to exchange with the Publisher about its activities.
    The User shows his consent to contract by filling out the appropriate contact form and disclosing his contact information. The Publisher executes the contract by responding to the User's request and sending the information to the user by email (or if necessary by post). This contractual execution involves knowing the identity of the user and the possibility of interacting with him. The Publisher may also process certain data on the basis of legitimate interest (including to ensure the security of the Site) or on the basis of the User's express consent (when the Publisher will specifically mention it on the contact form and collect consent via a checkbox).
    3) Recipients of collected data
    The database created when a user's request is sent through a contact form is strictly confidential. The Publisher undertakes to take all appropriate necessary precautions, organizational and technical measures to preserve the security, integrity and confidentiality of the Data and, in particular, to prevent it from being distorted, damaged or accessed by unauthorized third parties.

User Data will be erased on express expiration of shelf-life.
    In addition, the Publisher is likely to keep Data permanently anonymized for the purpose of producing statistical studies. Under no circumstances do these studies identify Users, and focus only on trends from their aggregate data.
    6) Security
    The Publisher takes appropriate technical and organizational measures to ensure the security of the Data and prohibit unauthorized access or disclosure of User Data. However, the Publisher cannot guarantee the elimination of any risk of misappropriation, tampering, illegal reproduction or misuse of the Data.

    2) How can the User manage Cookies?
    The User is first informed that the Publisher's partners and any other third parties may be required to deposit Cookies on the Site. Only the issuer of a Cookie is likely to read or change information contained in it, and the Publisher has no access or control over Cookies that third parties may be required to use. The issuance and use of Cookies by third parties is subject to the privacy policies of these third parties in addition to the provisions of this Policy. As a result, the User is invited to visit the websites of these third parties for more information about the Cookies they save and how the User can manage them.

    The agreement given by the User is only valid for a duration specific to each Cookie  from the first deposit in the equipment of the user's terminal, following the expression of the user's consent.
     B. Refusal of Cookies
    If the User refuses to register Cookies in their device or browser, or removes those registered in the device, the User is informed that their browsing and experience on the Site or Application may be limited. This could also be the case where the Publisher or one of its providers could not recognize, for technical compatibility purposes, the type of browser used by the terminal, the language and display settings, or the country from which the terminal appears to be connected to the Internet. If so, the Publisher disclaims any responsibility for the consequences of the degraded operation of the Services resulting (i) from the user's refusal of Cookies (ii) the Publisher's inability to register or consult the Cookies necessary for their operation as a result of the User's choice.
    C. Configuration of navigation software
    Users can set up their navigation software so that Cookies are stored in the terminal or, on the contrary, rejected, either systematically or depending on their sender. Users can also set up their navigation software so that cookies are accepted or rejected on an ad hoc basis, before a Cookie is likely to be registered in their device. In this case, the Publisher cannot guarantee that the Cookies used on its Site will be registered or rejected by this means.
